Abstract
A sensor control apparatus which receives from a gas sensor () a sensor output signal Ip corresponding to the concentration of a specific gas component, and a pressure signal P output from a pressure sensor (). The sensor control apparatus includes a computation section () which computes a specific component concentration which is corrected based on the pressure signal P so as to eliminate the influence of the pressure of the gas. The sensor control apparatus includes response adjustment sections () and () for adjusting the response rates of the sensor output signal Ip and the pressure signal P before being input to the computation section (), the response rate exhibiting a time variation of the corresponding signal to a change in the pressure of the gas, such that the response rate of the sensor output signal Ip or the response rate of the pressure signal P, whichever is faster, approaches the slower of the two.
